Answer:
Have the company install insulated sleeves over powerlines.
Explanation:
Answer:
Static Friction
Explanation:
To prevent slipping means to prevent the relative motion between the ground and the feet. It is the static friction that opposes the relative motion of the feet with respect to the ground.
The load is 17156 N.
<u>Explanation:</u>
First compute the flexural strength from:
σ = FL / π
= 3000 (40 10^-3) / π (5 10^-3)^3
σ = 305 10^6 N / m^2.
We can now determine the load using:
F = 2σd^3 / 3L
= 2(305 10^6) (15 10^-3)^3 / 3(40 10^-3)
F = 17156 N.
Answer:49.3
Explanation:
Given
mass of water
mass of tank
initial of temperature of water =
initial of temperature of tank=
Specific heat of water =4.184kJ/kg k
Specific heat of copper=0.386 KJ/kg k
From first law of thermodynamics we have
Given tank is insulated thus Q=0
work will be negative as it is being done on system
